Actually Dave, testing something like that where the difference might be
subtle, I wouldn't use 2 step tablets, but cover half the width of one
step tablet with the material. Step tablets, at least the 2115 I use,
have variations from strip to strip. Of course sometimes they don't, but
.... often they do. Using the same strip is easy & (fairly) definitive.
I recently tested saran wrap and a sheet of clear plastic, by the way.
Both showed same difference...
But speaking of step tablets, Tamara should get one... then she'll know
what if anything she's doing wrong. For a beginner to judge "dense
negative," or "deep shadows," or whatever is nearly impossible... In fact
it's not easy for old timers... development of the film can give
different colors and the effect very deceptive.
